Is it possible to do an update to the modules over a wireless connection?

Short answer, no. The SubGig BridgeBee modules are designed to operate at 315MHz which is outside of normal ISM bands and is subject to FCC part 15.231. These requirements impose restrictions on bandwidth and thus to not allow for over the air updates. Firmware updates are done through the serial port so field updates can be performed by a host processor.
